    Notes: [Auszug] The species 0. perennis is mostly cross-pollinated and it has a wide range of variation with a number of distinct geographical races. In the work recorded here a Cam-bodian type of O. perennis Moench was used and Belling's simple acetocarmine technique adopted. Twelve pachytene bivalents were ...

    On the luminescence of TlCl+KCl phosphor (1962)
    Springer
    The European physical journal 167 (1962), S. 20-25 
    Details
    ISSN: 1434-601X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract The measurements on the luminescence spectra of TlCl+KCl mixed phosphor under low energy cathode rays at 80° K have been presented here. The reflectance as well as excitation spectra of this mixed phosphors have also been studied. The X-ray diffraction studies of the samples along with the optical studies show that the mixed phosphor consists of two phases: (1) KCl:Tl (2) TlCl:K. It has been observed that the emission bands due to thallous chloride are gradually quenched with the increase in potassium chloride content of the phosphor; further, the emission bands supposed to be due to KCl:Tl phosphors gradually appear. Since some of the emission bands obtained with KCl:Tl phosphors at high thallium content are also present in the luminescence spectra of thallous chloride it is suggested that such bands should be attributed to undissociated thallous chloride present in KCl:Tl phosphor. The quenching of thallous chloride emission by the incorporation of potassium chloride in the system has been explained as being due to the absence of stoichiometric excess of thallium in such mixed system. The results also show that the absorption spectra of the mixed system is determined by the minor components KCl:Tl. This indicates that the absorption spectra of KCl:Tl phosphor should not be affected by the presence of undissociated thallous chloride.

    Isolation and fusion studies on protoplasts from pollen tetrads (1977)
    Springer
    Cellular and molecular life sciences 33 (1977), S. 182-184

    Notes: Summary different enzymes were tested for isolation of intact protoplasts from pollen tetrads. About 80% isolation was achieved from pollen tetrads of Cajanus cajan and Zea mays and about 60% from Luffa cylindrica and Lycopersicon esculentum after 4 h of treatment with 5% cellulase. When these mononucleate protoplasts were incubated in presence of 0.05 M CaCl2 in 0.3 M glucose at pH 10.5, 70–80% fusion was achieved. Fusion was rare in sodium nitrate solutions.

    Notes: Summary A1 and A2 cells of the median neurosecretory group are filled with PF stained neurosecretory material between the first 24 to 48 h of the earlier moult in each instar followed by immediate release before the next moult at 72 h, while loaded posterior and lateral neurosecretory cells also appear from the 3rd and 5th instars onwards. Corpora cardiaca, corpora allata and prothoracic glands increase in size in each instar.

    The level of action of 2,4-D on transcription (1978)

    Notes: Summary In mature cells, 2,4-D retards transcription when it is applied before3H-uridine incorporation. But transcription is accelerated when it is applied after feeding with3H-uridine. It has been suggested that the action of 2,4-D on transcription is only at the level of initiation.
